NeuroMove works by detecting the attempts to move a muscle group sent from the brain. These attempts are shown in the display as significant increases in the signal over regular muscle activity. The built-in microprocessor intelligently distinguishes between regular muscle activity, muscle tone, noise and real attempts in the EMG. When a real attempt is detected, the unit “rewards” the patient with a few seconds of muscle contraction, where the visual and sensory feedback serves as an important element in relearning the movement. This is similar to the well known learning technique of “Pavlov’s Dog”.
